Field Description
Channel Name Displays the name assigned to the channel.
Description Type a description of the channel.
Administrative Check Enable to make the channel active. Clear Enable to make the channel inactive.
Speed Choose the operating speed of the channel. If the connected device can negotiate the link speed with the channel, choose Auto (autonegotiation).
Default: Auto
Duplex Choose the duplex mode of the channel:
• Auto—(Autonegotiation). The connected device can negotiate the duplex mode with the channel. If the channel is not connected or has not
completed negotiation, the status is Auto.
• Half— (Half-duplex mode). The connected device must alternate sending or receiving data.
• Full— (Full-duplex mode). Both devices can send data at the same time.
Default: Auto
Administrative Mode Choose one of the following administrative modes:
• Access—The channel is in permanent nontrunking mode and negotiates to convert the neighboring link into a nontrunk link even if the
neighboring interface is a trunk interface. If you choose this option, also choose an Access VLAN. An access port belongs to and carries the traffic of
only one VLAN (unless it is configured as a voice VLAN port).
• Trunk—The channel is in permanent trunking mode and negotiates to convert the neighboring link into a trunk link even if the neighboring
interface is not a trunk interface. If you choose this option, also choose whether to allow All VLANs or specified VLAN IDs.
• Dynamic Auto—The channel converts the link to a trunk link if the neighboring interface is set to trunk or desirable mode. This mode is the default
setting. If you choose this option, specify an Access VLAN to use when the link is in access mode. Also specify whether to allow All VLANs or specified
VLAN IDs when the link is in trunk mode.
• Dynamic Desirable—If the neighboring interface is set to Trunk, Dynamic Desirable, or Auto mode, the channel converts the link to a trunk link. If
you choose this option, specify an Access VLAN to use when the link is in access mode. Also choose whether to allow All VLANs or specified VLAN IDs
when the link is in Trunk mode.
• Routed—The channel acts like a port on a router but does not have to be connected to a router. A routed port is not associated with a particular
VLAN, as is an access port. A routed port behaves like a regular router interface, except that it does not support VLAN subinterfaces. Routed ports
can be configured with a Layer 3 routing protocol. A routed port is a Layer 3 interface only and does not support Layer 2 protocols, such as DTP and
STP. Routed ports are supported only on switches running the IP base or IP services image.
Default: Dynamic Auto
Access VLAN Choose the VLAN that the channel belongs to and carries traffic for when the channel is configured as or is acting as a nontrunking interface.
Allowed VLAN Choose the VLANs for which this channel handles traffic when the channel is configured as or is dynamically acting as a trunking interface:
• To allow traffic on all available VLANs, click All VLANs.
• To limit traffic to specific VLANs, click VLAN IDs and enter the VLAN numbers.
Native VLAN Choose the VLAN that transports untagged packets.
